Professor Stuart has made seminal contributions to understanding how information is processed by individual nerve cells in the brain. He developed and implemented techniques for making electrical recordings from the fine processes of nerve cells called dendrites. These techniques, which are used throughout the world, led to a series of classic papers describing the initiation and spread of nerve impulses in different nerve cell types. He is a world expert on the physiology of dendrites and co-edited the first book devoted exclusively to this subject. He continues to make outstanding contributions to our understanding of information processing in the brain.
